I am looking for some input concerning VLANs on the 3C16475BS or Baseline 2226 Plus. One of my clients has one of these. I had an odd thing happen with it yesterday. VLAN 3 had ports 17/18/19/20 working fine. The client is adding another office so I added ports 6/8/9 to VLAN 3 in config, then clicked apply to make them active. Everything looked good from the status when I checked and the ports showed active links. Then today I get a call from the client saying they can't access anything from the connected work stations on that VLAN. I get to the client location and check from the work station. Sure enough, the link is there, but no IP address assigned to the computer!
I connect my Test-Um testset no DHCP! None of the ports in VLAN 3 would talk to one another! I login to the switch and look at the config, everything looks OK. So I remove the VLAN 3 and then add it back in and everything works!!??
This is puzzling! Has anybody else had an experience like this with 3COM switches?
This switch was replaced in January 2008 because the previous one would lose the config to default every two weeks! I double checked the manual, and it did not say anything about the order in which one can modify a VLAN. By this I mean, if adding or removing ports do you remove the entire VLAN, or just remove or add ports as required, then click apply... In this case that did not seem to work on an existing VLAN. It killed it! Does anyone think this is a firmware bug? Btw, the switch has up-to-date firmware according to the 3COM website.
Any input is appreciated...
Thanks in advance!
